It is with great regret that the Mathematics Department must note the passing last week, at age 81, of our colleague Professor Emeritus and Distinguished Research Professor Veeravalli Seshadri Varadarajan.

Dr. Charles (Chuck) J. Stone passed away on April 16, 2019. Chuck received his Ph.D. at Stanford University in 1961 under the direction of Samuel Karlin, and he joined the UCLA Department of Mathematics faculty in 1964.

A key element in the UCLA team’s system is its ability to consistently generate water droplets of the same size and constant flowing speed. These water beads enable the system to effectively capture water vapor, without causing significant pressure drop, and hence fan power consumption.
